Uuuh baby, let's do the Limerick again... I never know whether I should love them or hate them. Sometimes I hate them because of their mind-penetrating structure and the shrink-wrapped sentences. Sometimes I love them because of the slight humour you cannot avoid while writing them.
Whatever you can do with limericks and whatever you can not do with them (not mentioning the things you can do without them :), there is one thing that you can not do at all: being indirect. As to my humble opinion, everything you will ever write in a limerick will be exactly what you want to say, nothing more, nothing less. This one is no exception.
